Description

Technical Field

[0001] This utility model relates to the field of air conditioning unit technology, and more specifically, to a clean air conditioning unit. Background Technology

[0002] An air handling unit is an air handling device assembled from various air handling functional sections. It is suitable for air conditioning systems with a resistance greater than 100Pa. The air handling functional sections of the unit include: air mixing, flow equalization, filtration, cooling, primary and secondary heating, dehumidification, humidification, supply fan, return fan, water spray, noise reduction, heat recovery, and other units.

[0003] Patent application number 202320772567.5 discloses an energy-efficient and high-performance water-cooled clean air conditioning unit, including a housing. The housing has a condensation tank and a heat dissipation tank inside. An air inlet slot is formed on one inner wall of the condensation tank, and a filter screen is bolted into the air inlet slot. An air intake fan is bolted onto the inner wall of the air inlet slot near the filter screen. A condensation pipe is installed inside the condensation tank, and a heat dissipation pipe is installed inside the heat dissipation tank. Water channels with equal spacing and horizontal arrangement are formed on the bottom inner wall of the heat dissipation tank. This utility model, through the design of the heat dissipation fan and water channels, allows the heat dissipation fan to cool the outer wall of the condensation pipe when activated, and the filter screen to filter dust. When the heat dissipation pipe comes into contact with air, water droplets condense and drip onto the outer wall of the condensation pipe through the water channels, thus cleaning the condensation pipe. The heat dissipation fan makes the heat exchange more efficient, resulting in a more efficient cooling system.

[0004] Regarding the aforementioned technologies, the cooling fan can cool the outer wall of the condenser tube and the filter screen can filter dust. When the condenser tube comes into contact with air, water droplets will condense and drip onto the outer wall of the condenser tube through the water channel, thus cleaning the condenser tube. Although a filter screen is installed in the air inlet channel to filter dust, there is no protective component at the air inlet channel port. When the equipment is not used for a long time, the filter screen may become covered with dust, which may affect the subsequent use of the equipment. Utility Model Content

[0005] To solve the above problems, this utility model provides a cleanroom air conditioning unit, which adopts the following technical solution:

[0006] A cleanroom air conditioning unit includes an air conditioning unit body, a base fixedly mounted on the bottom of the air conditioning unit body, drive wheels at the four corners of the bottom of the base, shock-absorbing components between the drive wheels and the base, two symmetrically distributed storage slots at the bottom of the base, a support component below the base, an air inlet frame on one side of the air conditioning unit body, and an exhaust frame on the top of the air conditioning unit body. Filters are fixedly installed inside the air inlet and exhaust frames near the air conditioning unit body, and dustproof components are provided on the side of the air inlet and exhaust frames away from the air conditioning unit body. A mounting box is provided on one side of the air inlet and exhaust frames, and multiple support rods arranged in a linear array are rotatably mounted inside the air inlet and exhaust frames. Baffles are fixedly fitted on the sidewalls of the support rods, and one end of each support rod on the same side rotatably extends into the mounting box of the same group. A drive component is provided between the ends of the support rods on the same side extending into the mounting box of the same side.

[0007] By adopting the above technical solution, the equipment can be moved by the drive wheels, which improves the ease of movement. Shock-absorbing components are installed between the drive wheels and the base to provide cushioning and maintain stability during movement. Once the equipment is in place, the support components drive the base and the air conditioning unit to rise as a whole, lifting the drive wheels off the ground and providing stable support for the air conditioning unit. Dust-proof components are installed at the ends of the air inlet and outlet frames furthest from the air conditioning unit to filter dust from the air entering the unit. It not only serves as a dustproof barrier during equipment use but also when the equipment is not used for extended periods, helping to prevent dust from entering the air conditioning unit and maintaining its performance. Multiple baffles are installed within the air inlet and exhaust frames to seal them, further enhancing dust prevention. Sealing gaskets on the side walls of the baffles ensure a tight seal between adjacent baffles, further maintaining the dustproof effect. A drive assembly rotates the support rods on the same side, creating gaps between the baffles to facilitate airflow and adjust the air intake and exhaust volume.

[0008] Furthermore, the shock absorption assembly includes four shock absorbers disposed at the four corners of the bottom of the base. Each shock absorber has a spring sleeved on the side wall of its telescopic shaft, and the end of the shock absorber's telescopic shaft is connected to the top of the drive wheel on the same side.

[0009] By adopting the above technical solution, the staff can drive the equipment to move by driving wheels. When the equipment moves, the springs absorb the vibration force generated by the equipment, and then the shock absorbers counteract the rebound force generated by the same group of springs, achieving the effect of shock absorption and buffering, which helps to maintain the stability of the air conditioning unit's movement.

[0010] Furthermore, the support assembly includes two base plates disposed below the base. The two base plates are symmetrically distributed below the base. Two symmetrically distributed cylinders are fixedly installed on the inner walls of the top of each of the two storage slots. Support blocks are fixedly installed at the piston shaft ends of each cylinder. The bottom ends of the two support blocks on the same side are fixedly connected to the top of the base plate on the same side. Two symmetrically distributed stabilizing plates are fixedly installed on both sides of the two base plates. Anti-slip pads are provided at the bottom ends of the base plates and stabilizing plates.

[0011] By adopting the above technical solution, when the equipment is moved to a suitable placement point, the base plate on the same side is driven to descend and contact the ground by two cylinders on the same side. Then, the base and the air conditioning unit body rise under the driving force of the cylinders, thereby causing the drive wheel to leave the ground, which can play the role of supporting and stabilizing the equipment and help maintain the stability of the equipment.

[0012] Furthermore, the dustproof component includes a mounting frame fixedly installed on the side of the air inlet frame and the air outlet frame away from the air conditioning unit body. Each mounting frame has a slidably installed frame, and each frame is provided with dustproof cotton. Slider blocks are fixedly installed on both sides of the two frames, and the inner walls of the two mounting frames are provided with grooves that match the sliders on the same side.

[0013] By adopting the above technical solution, the side of the air inlet frame and air outlet frame away from the air conditioning unit body is equipped with dustproof cotton. When the equipment is running, the dustproof cotton can filter dust in the air, thus preventing dust. Moreover, the dustproof cotton not only plays a role in preventing dust during equipment use, but also when the equipment is not used for a long time. This helps to prevent dust from entering the air conditioning unit body and helps maintain the equipment's performance. The dustproof cotton is fixed by a slider and a groove opened on the inner wall of the mounting frame on the same side, which facilitates disassembly and cleaning by the staff and helps maintain the dustproof effect of the equipment.

[0014] Furthermore, multiple rubber rods arranged in a linear array are fixedly installed on one side of each of the two frames, and grooves matching the rubber rods on the same side are opened on the inner wall of one side of each of the two mounting frames.

[0015] By adopting the above technical solution, when the staff places the frame and dustproof cotton into the same side mounting frame, the rubber rod installed on one side of the frame engages with the groove opened in the inner wall of the same side mounting frame. The friction generated by the engagement of the rubber rod and the groove on the same side helps to maintain the stability of the dustproof cotton installation.

[0016] Furthermore, the drive assembly includes a geared motor fixedly installed on the inner wall of the mounting box, and sprockets are fixedly sleeved on the support rods on the same side, passing through one end of the mounting box on the same side. A toothed chain is sleeved between the sprockets on the same side, and the ends of the output shafts of the two geared motors are fixedly connected to the opposite end of one of the support rods on the same side.

[0017] By adopting the above technical solution, the support rod connected on the same side is driven to rotate by the geared motor, and the support rod drives the sprocket on the same side to rotate. Then, through the cooperation of the toothed chain and multiple sprockets, the support rod on the same side drives the baffle to rotate synchronously, so that a gap is created between the baffles on the same side, which facilitates the flow of gas in and out, and can also play the role of adjusting the air intake and exhaust volume of the equipment.

[0018] Furthermore, a protective cover is fitted on the outer side of both toothed chains, and two symmetrically distributed connecting blocks are fixedly installed on the sidewalls of both protective covers. The opposite sides of the two connecting blocks on the same side are fixedly connected to the inner wall of the opposite side of the mounting box on the same side.

[0019] By adopting the above technical solution, the protective cover on the outside of the toothed chain helps to release the toothed chain, which helps to prevent the toothed chain from separating from the sprocket on the same side and helps to maintain the stability of the toothed chain and sprocket transmission.

[0020] In summary, this utility model has the following beneficial technical effects:

[0021] (1) In this utility model, dustproof components are provided at the ports of the air inlet frame and the air outlet frame. They not only play a role in preventing dust during use, but also play a role in preventing dust when the equipment is not used for a long time. This helps to prevent dust from entering the air conditioning unit body and helps to maintain the equipment's performance. The dustproof cotton is locked and fixed by the slider and the groove opened on the inner wall of the mounting frame, which makes it easy for the staff to disassemble and clean it later, and helps to maintain the dustproof effect of the equipment.

[0022] (2) In this utility model, the baffles in the air inlet frame and the air outlet frame are used to block the air inlet frame and the air outlet frame, thereby achieving the effect of dust prevention. The support rod and the baffles can be rotated by the drive component, which makes it easy to adjust the air inlet and air outlet volume of the equipment, and can also adjust the exhaust direction of the equipment.

[0035] The following is combined with Figure 1-7 The utility model is described in further detail.

[0036] Please see Figure 1-7 A cleanroom air conditioning unit includes an air conditioning unit body 2. A base 1 is fixedly installed at the bottom of the air conditioning unit body 2. Each of the four corners of the bottom of the base 1 is provided with a drive wheel. A shock-absorbing component is provided between the drive wheel and the base 1. The shock-absorbing component includes four shock absorbers 7 set at the four corners of the bottom of the base 1. Springs 8 are sleeved on the side walls of the telescopic shafts of the shock absorbers 7.

When the equipment is in use, the staff can drive the equipment to move through the drive wheels, which is conducive to improving the convenience of equipment movement. When the equipment moves, the springs 8 absorb the vibration force generated by the equipment, and then the shock absorbers 7 counteract the rebound force generated by the springs 8 in the same group, achieving the effect of shock absorption and buffering, which is conducive to maintaining the stability of the movement of the air conditioning unit body 2.

[0037] The base 1 has two symmetrically distributed storage slots 24 at its bottom. A support assembly is provided below the base 1, which includes two base plates 9 located below the base 1. The two base plates 9 are symmetrically distributed below the base 1. Two symmetrically distributed cylinders 11 are fixedly installed on the inner walls of the top of each of the two storage slots 24. Support blocks 10 are fixedly installed at the piston shaft ends of each cylinder 11.

Two symmetrically distributed stabilizing plates are fixedly installed on both sides of the two base plates 9. Anti-slip pads are provided at the bottom ends of the base plates 9 and the stabilizing plates. When the equipment is moved to a suitable placement point, the two cylinders 11 on the same side drive the base plate 9 on the same side to descend and contact the ground. Then, the base 1 and the air conditioning unit body 2 rise under the driving force of the cylinders 11, thereby causing the drive wheels to leave the ground, which can play the role of supporting and stabilizing the equipment and helping to maintain the stability of the equipment during use.

[0038] An air inlet frame 4 is provided on one side of the air conditioning unit body 2, and an exhaust frame 6 is provided at the top of the air conditioning unit body 2.

[0039] The air inlet frame 4 and the air outlet frame 6 are located away from the air conditioning unit body 2. The dustproof cotton 3 is installed on the side away from the air conditioning unit body 2. When the equipment is running, the dustproof cotton 3 can filter dust in the air and prevent dust. The dustproof cotton 3 not only prevents dust during the use of the equipment, but also prevents dust when the equipment is not used for a long time. It helps to prevent dust from entering the air conditioning unit body 2 and helps to maintain the equipment's performance. The dustproof cotton 3 is fixed by the sliding block 23 and the sliding groove opened on the inner wall of the mounting frame 12 on the same side, which makes it easy for the staff to disassemble and clean, and helps to maintain the dustproof effect of the equipment.

[0040] Multiple rubber rods 14 arranged in a linear array are fixedly installed on one side of each of the two frames 13. The inner wall of one side of each of the two mounting frames 12 has a groove that matches the rubber rods 14 on the same side. When the staff places the frame 13 and the dustproof cotton 3 into the mounting frame 12 on the same side, the rubber rods 14 installed on one side of the frame 13 and the grooves on the inner wall of the mounting frame 12 on the same side will engage.

[0042] Multiple baffles 15 are provided inside the air inlet frame 4 and the air outlet frame 6, which can block the air inlet frame 4 and the air outlet frame 6 to achieve a further dust prevention effect. The side walls of the baffles 15 are provided with sealing gaskets, which helps to maintain the sealing of the two adjacent baffles 15, thereby helping to maintain the dust prevention effect of the equipment. The support rod 20 connected to the same side can be driven to rotate by the geared motor 17, and the support rod 20 drives the sprocket 19 on the same side to rotate. Then, through the cooperation of the toothed chain 18 and multiple sprockets 19, the support rod 20 on the same side synchronously drives the baffles 15 to rotate, creating gaps between the baffles 15 on the same side, which facilitates the flow of gas in and out, and can also play a role in adjusting the air intake and exhaust volume of the equipment.
